Yuav ua li cas receptors teb rau acetylcholine?
Acetylcholine receptors (AchRs) raug cais los ntawm lawv lub peev xwm los teb rau ob leeg muscarine (M1-M 5) los yog nicotine (nAchR) Muscarinic receptors yog classic G protein-coupled receptors (GPCRs), ua ke rau Gi, uas inhibits cAMP ntau lawm. Nicotinic AchRs yog ligand-gated voltage channels.
Dab tsi receptors khi rau thiab teb rau acetylcholine?
Acetylcholine hauv ANS
ACh khi rau muscarinic receptors (M2) uas pom muaj nyob hauv cov hlwb suav nrog cov sinoatrial (SA) thiab atrioventricular (AV) nodes. Muscarinic receptors yog txuas rau Gi-protein; yog li ntawd, vagal activation txo cAMP.
Cov receptors rau acetylcholine nyob qhov twg?
